weblogic 10.3.6サーバーにある EJB に属する ejb メソッドを実行しています。このサーバーは、Solaris-10 64 ビットマシンにあります。EJB クライアントは、Windows XP 32 ビットマシンにあります。
この ejb メソッドを (junit テスト ケース内で) 実行すると、この奇妙な例外が発生します。さまざまな理由を考えて何度かグーグルで検索しましたが、まだ解決策を見つけることができません。
java.io.DataInputStreamのソース コードを確認したところ、このjava.io.DataInputStream.readInt()メソッドは、この入力ストリームが 4 バイトを読み取る前に最後に到達すると、この例外をスローします。
この問題について何か考えがありますか?前もって感謝します。
